This paper presents data from Brazilian Patent Office (Instituto Nacional de Propriedade Industrial, INPI) and compares them with data from the United States Patent Office (USPTO). Developing countries have technological activities that are important locally but not significant at international level (imitation, local learning, adaptation of foreign innovations). These activities might be patentable only at national level. Therefore, the study of domestic patents of developing countries provides a broader picture than USPTO patents. This paper compares 8309 INPI patents with 475 USPTO patents (between 1980 and 1995). Domestic patent data show peculiarities in the Brazilian case, possibly shared with other countries in similar technological level: (a) high share of individual patents; (b) foreign-owned firms with important activities; (c) low firm involvement in R&D activities. Some characteristics are shared with developed countries: (a) domestic firms as the major patentees; (b) according to firm size, there is a U-shaped distribution of patents; (c) evidences of multi-technology large firms; (d) a relatively small share of firms have more than one patent in the whole period. The contrast between USPTO and national patenting statistics shows different rankings according to ownership structure, leading firms, industrial sectors, and international patent classification. These differences highlight sources of international competitiveness and point to weaknesses in Brazilian innovative activities. This paper concludes evaluating the contributions (and weaknesses) of this database for the evaluation of the Brazilian National System of Innovation.  相似文献

Patents are key strategic resources which enable firms to appropriate innovation returns and prevent rival imitation. Patent examiners – individuals who may be subject to various sources of bias – play a central role in determining which inventions are awarded patent rights. Using a novel dataset, we explore if one increasingly prevalent source of bias – political ideology – manifests in examiner decision-making. Reassuringly, our analysis suggests that the political ideology of patent examiners is largely unrelated to patent office outcomes. However, we do find evidence suggesting politically active conservative-leaning examiners are more likely to grant patents relative to politically active liberal-leaning examiners, but only for patent applications where there is ambiguity regarding what constitutes patentable subject matter and hence examiners have greater discretion.  相似文献

以往研究基于信号理论,强调专利信号对企业资源获取的积极影响,而未能解决企业如何应对专利流失的问题。本研究使用我国专利密集型产业的上市公司样本,探讨了企业专利数量的减少如何影响企业后续专利申请行为。通过构建2008-2017年中国专利密集型上市公司的面板数据,使用负二项回归进行分析,发现企业专利数量的减少会触发企业的积极响应,促使企业申请更多的专利来恢复专利的信号功能。同时,企业的响应力度会受到内外情境因素的影响,其中企业连锁董事网络的中心地位和政治联系具有消极的调节作用,而组织绩效则具有积极的调节作用。本研究从信号丢失的全新视角揭示了企业如何解决专利流失问题,并为我国企业的专利申请战略提供了理论参考。  相似文献

专利技术许可已经成为开放式创新时代企业获取创新利益的重要方式,而何时进行专利许可是企业面临的重要决策问题。本文根据专利的法律化过程将专利许可时间分为专利申请-公开之间、公开-授权之间以及授权后,重点考察不同创新规模条件下企业的专利许可时间决策差异。通过将专利公开效应与授权效应纳入到企业专利许可时间决策模型,从理论上推导出企业创新规模与专利许可时间决策的关系,即:(1)企业创新规模增加会导致专利申请-公开之间许可的概率增加;(2)企业创新规模增加会导致专利公开-授权之间许可的概率先增加后降低,即企业创新规模对专利公开-授权之间许可概率的影响呈倒U型;(3)企业创新规模增加会导致专利授权后许可的概率降低。然后,本文利用2001-2015年中国企业在国家知识产权局申请且第一次备案许可的11865条发明专利进行实证研究,结果验证了以上所有理论命题。本研究从理论上揭示了不同创新规模企业的专利许可时间决策机制,对我国企业技术转移策略选择以及技术转移政策设计具有重要实践启示。  相似文献

Business cycles modify firms’ incentives to innovate and the direction of innovation. By introducing a new measure of patent unconventionality this paper explores the impact of the business cycle on firms’ technological search strategies. We find that during upturns firms generate inventions characterized by a higher level of technological unconventionality. We also find that financially resilient and diversified firms produce more unconventional patents. While patent unconventionality is associated with technological impact and market value, firms extract more value by investing in unconventional inventions in downturns.  相似文献

This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions. Using global patent data, this paper empirically investigates the importance of both the quantity and quality of innovation on economic growth, controlling for past measures of inventive inputs. Moreover, our research examines how innovation inputs can be translated into per capita growth under the various economic structures and stages of economic development. Based on a sample of 58 countries for the period 1980–2003, our empirical results indicate that countries hosting firms with higher quality patents also have higher economic growth. Furthermore, we have some evidence that those countries that increase the level of patenting also witness a concomitant increase in economic growth.  相似文献

This paper presents an example of the use of patent statistics as a technology indicator in one industry. The first part deals with the problem of interpretation. Through examination of several other partial technology indicators, it is concluded that at least in this industry, patent statistics provide a reliable indicator, not only for the timing of inventions, but for the timing of innovations and diffusion as well. The reason is that the intervals between the stages in the innovation process are very short. This contradicts evidence from many other industries, and it is therefore emphasized that generalizations are unwarranted.The second part of this paper deals with the possible causes of technological change in Norwegian whaling. The methodology is inspired by J. Schmookler's work. Thus, the patents are correlated with other indicators of economic development in the industry. But while Schmookler's view is that the patent activity is determined by social demand and economic growth, the conclusions for the Norwegian whaling industry point in the opposite direction: the technological transformation that took place during the 1920s and early 1930s was forced upon the firms in their efforts to cut costs, which was achieved by rationalizing production and catching methods in line with a downward price trend for whale oil.  相似文献

This paper revisits the patents debate and considers the role of intellectual property rights and their impact on society in the context of inventions designed to protect global common pool resources (CPRs) such as public health and the environment. A review of the theoretical and empirical literature suggests that there has never been a clear consensus among researchers on the benefits of the patent system and intellectual property rights. As Robinson notes, “The patent system introduces some of the greatest of the complexities in the capitalist rules of the game and leads to many anomalies.” We explore these anomalies by specifying a taxonomy of patents for different classes of inventions, including inventions to protect CPRs. This includes vaccines and inventions that reduce externalities, such as, CFC gases and greenhouse gas emissions. In these instances, the effectiveness of innovations depends critically on rapid global diffusion. Our theoretical analysis utilises Ostrom's CPR dilemma to analyse the complexities surrounding innovation and CPRs.We find that the effectiveness of innovations to protect CPRs depends on industrial characteristics and the wider regulatory environment. Empirical evidence is brought to bear on these conclusions via 2 case studies that each embodies a natural experiment; one on vaccines pre- and post-TRIPS and one on environmental technologies to reduce CFC gases and CO2 emissions with and without an agreed UN Protocol. The insights gained are explored in our policy section. Our analysis suggests the need for a more nuanced approach to patent policy that is embedded in the wider context of innovation systems and takes account of the anomalies raised by CPRs. For CPR protecting innovations subject to positive network externalities, we advocate that policy should prioritise diffusion over private incentives for R&D and use alternative policies to patents to stimulate investment in R&D.  相似文献

We propose an empirical strategy to estimate competition in innovation markets. Our method relates firms’ market return on equity to information about patent citation patterns. Two innovations are implemented in the methodology. First is the application of daily abnormal stock returns rather than annual measures of Tobin's q. Second is the creation of citation patterns related to the area of science a firm patents in as represented by the detailed patent classification system. We find that markets positively reward firms when patents are granted. We further find that firm's market value increases when its patent portfolio is cited. We find evidence of competition in innovation markets. The market reacts at the time that the citation occurs and does not anticipate future citations at the time of patenting. Holding this effect constant, we find that citations from patents in the same area of science tend to reduce market value. We interpret these findings as consistent with more citations indicating more valuable intellectual property but citations from competing technologies decreasing it.  相似文献

This study examines the effect of antitrust regulation of patent consolidation on the development of follow-on innovations. Our reconciliation of the various strains of literature hypothesizes that in sectors where cumulative innovation is crucial to firms’ market operations, a firm that consolidates patents for substituting technologies for its already-possessed technologies discourages market competitions and follow-on innovation by competitors. In this case, antitrust regulation of patent consolidation is anticipated to positively affect competitors’ follow-on innovation. We empirically test this hypothesis with the case of the US Department of Justice's regulation of Novell's software patent transfers to four large proprietary software companies (i.e., Microsoft, Oracle, EMC, and Apple) in 2011. Our analyses using US patent, trademark, and copyright data have found evidence corroborating our hypothesis. Our research provides policy and scholarly implications regarding how antitrust law can be a complementary institution to the patent law for promoting innovation.  相似文献

Technological innovation plays a critical role in economic growth. The most advanced and new technologies are created by leading firms in developed countries. Global expansion, strategic outsourcing or off-shoring in leading companies has been growing to enrich their competitive advantage, while technology transfer of leading firms has been of more interest to emerging or developing countries for catching up and following the trajectory of economic growth proved in developed countries. Among various channels to acquire new technologies from leading firms, foreign direct investments (FDI) is one of the most effective channels through which technology can be transferred to subsidiaries in emerging markets. However, empirical study on the roles of technology transfer and the feedback loop from FDI remains still scarce. Thus, the purpose of this study is to analyze the effects of FDI on businesses in partial or complete foreign ownership, with a special emphasis on technology transfer, and to assess the impact of foreign companies on domestic firm performance through technology transfer from foreign companies. This paper aims at investigating the investment climate for foreign investments and intensifying technology transfers and innovations in the Croatian economy. 145 firms responded to the survey we conducted for foreign investment enterprises in Croatia. Structural equation model is employed to examine the hypotheses with respect to effects of FDI on innovation activities of domestic Croatian firms. This study identified critical factors affecting technology innovation to Croatian firms. The results provide empirical evidence that the innovation activities in subsidiaries have a positive influence toward technology transfer from multinational corporations.  相似文献

In recent years, firms have increasingly contributed to and been confronted with a patent landscape characterized by numerous but marginal inventions, overlapping claims and patent fences. As a result, firms risk their patent applications to be pre-empted or to be infringed upon by rivals. While both aspects constitute major challenges for the appropriation of returns to inventive activity, extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems. In this paper, we investigate the effect of pre-empted and infringed patents on firms’ engagement in in- and cross-licensing. Based on a sample of more than 1100 German manufacturing firms our results show that firms engage in in-licensing as a reaction to pre-empted patents and in cross-licensing if their protected IP was infringed upon. However, these effects vary depending on the fragmentation of technology fields and whether the firm operates in a discrete or complex product industry.  相似文献

The standard empirical framework for analysing the R&D-patents relationship is widened both by examining the different role of in-house and contracted R&D in the innovative performance of firms, and by considering patents and utility models counts as measures of innovation output. Patents and utility models are considered to approximate for significant and incremental innovations, respectively. Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990-1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs. The results indicate that significant innovations are mainly gestated in-house, whereas contracted R&D seems more orientated towards innovations of incremental nature.  相似文献

The mobility of inventors leaves behind their patented inventions at sourcing firms, yet there is little scholarly insight into how firms handle those intellectual properties. We investigate this important issue by developing a framework of tacit-codified knowledge interdependence. We theorize that tacit and codified knowledge offer the intellectual and legal pillars of corporate inventions, which complement each other in value creation. Inventor mobility decouples the two pillars and reduces the maintenance likelihood of the left-behind patents. The negative impact is greater for inventions that are complex or rely less on internal prior art because the tacit knowledge loss is more destructive and unrecoverable. However, when inventors move to competing or litigious target firms, the relationship between mobility and patent maintenance becomes less negative or even turns positive because the left-behind patents can be leveraged to hedge against the risk of knowledge leakage. Applying a two-stage Coarsened Exact Matching approach to construct a sample of 36,204 U.S. patents with comparable leaving and staying inventors from public firms between 1983 and 2010, we find strong evidence supporting our framework. Our findings highlight the intricate interdependence of tacit and codified knowledge in corporate inventions and add to the literatures on inventor mobility and intellectual property management.  相似文献
